Today more than 7,000 organizations including government agencies, insurers, and universities use Tableau, and that number has grown 40 percent in the last year. “I’ve never seen people get this excited about data,” says Ted Corbett, director of knowledge management at Seattle Children’s Hospital, where 150 staffers use Tableau for such tasks as scheduling operating rooms and clinic space. In the past year the company released an iPad app and service for media websites. Revenue is on track to nearly double, to $65 million, according to Tableau.
